Description

The invention relates to the construction and can be used in the external walls of residential, public and industrial buildings for various purposes.

According to the main author. St. No. 914737 is known a building element of the type of a wall panel of reinforced concrete, including rigid liners in its end parts and connecting elements between them. The butt inserts are made in the form of spatial reinforcement cages with reinforcement outlets, and the connecting elements in the form of flat reinforcement cages, each of which is installed with an overlap with the releases of spatial reinforcement cages 1..

The disadvantage of the known building element is the complication of the reinforcement of building elements of different widths, as well as elements with end parts of a complex configuration. In these cases, the implementation of end liners in the form of rigid spatial reinforcement cages leads to the need to increase their range, taking into account the change in the element width and configuration of the ends. In addition, with the developed configuration of the end parts of the element, especially the supporting sections, the use of rigid reinforcement cages does not ensure their safety under local loading, especially when exposed to dynamic (shock) load.

The purpose of the invention is to simplify the manufacturing technology, improve quality, reduce the metal consumption of building elements.

The goal is achieved by the fact that in the building element the spatial reinforcement cages located at the ends of the element are made of flexible ribbon-like fibromats interacting with reinforcement releases with flat reinforcement cages of the connecting elements.

Fibromats are reinforced fibrocarcasses of randomly bonded fibers made of, for example, steel wire segments with a diameter of 0.1 to 1 mm, a length of 20 to 300 mm, and an average distance between the fibers of 1 to 10 mm.

The distribution of fibers in a flexible fibromate can be volumetric (the fibers are randomly distributed over the volume of the fibromate), planar (the fibers are randomly distributed in the plane of the fibromate, if the thickness of the fibromate is less than the length of the fibers), axial (the fibromate has such an anisotropy axis relative to which more than 50% of the fibers are angle not exceeding 45 °). The type of flexible fibromat depending on the distribution of fibers in it, their length, and content is determined based on the operating conditions of the end parts of the building element. The length of the flexible fibromat is determined by the perimeter of the end part of the element and the size of the overlap with the flat reinforcement cages of the connecting elements (connecting frames).

The width of the flexible fibromate is assumed to be equal to the thickness of the end parts of the building element, and the thickness of the flexible fibromate is determined depending on the calculation and technological requirements and ranges from 20 to 100 mm.

FIG. 1 shows the proposed construction element, a general view; in fig. 2 - flexible ribbon-like fibromate in axonometry, general view.

The building element 1 contains end parts 2 reinforced with flexible tape-shaped fibromats 3, which have reinforcement releases 4. Issues of flat reinforcing cages 5 are introduced into reinforcement releases of fibromats.

Flexible ribbon-like fibromate 3 (Fig. 2) is capable of taking any shape depending on the configuration and dimensions of the end parts 2 of element 1. Fixation of flexible fibromate 3 (Fig. 1) is carried out at the sites of installation of embedded parts, at the places of overlap with flat reinforcing cages 5 and in specially provided places (the position of which is determined depending on the configuration of the end parts 2) with the help of a lead wire.

Fixation of flexible fibromate 3 in places of overlap with flat reinforcement cages, carried out by fitting flexible fibromat onto longitudinal rods 5 of flat framework, allows reducing the calculated length of overlap by 20-25% due to the effect of increased adhesion between longitudinal reinforcement and concrete reinforced with flexible fibromat .

The implementation of spatial reinforcement cages and end parts of an element made of flexible ribbon-like fibromats simplifies the manufacturing technology of building elements with end parts of a complex geometric shape (configuration), increases the reliability of the elements, first of all, the impact strength of elements nomenclature of spatial reinforcement cages and their metal intensity.

0 The application of the invention allows to reduce the laboriousness of the manufacture of reinforcement and the formation of elements, their intensity and range of reinforcement products.
